    Description, as the server wrote it
    Add a holiday rotation to a custody calendar made by make_custody_schedule: Thanksgiving, Christmas Eve/Day, Easter, US long weekends, UK bank holidays, Canadian and Australian public holidays, and school breaks alternating by year or split in half. Holidays override the regular rotation on those nights. Returns the updated calendar, overnight counts and new .ics and subscribe links.

      What this check looks for
    Description, as the server wrote it
    Turn a custody or parenting-time rotation (week on/week off, 2-2-3, 2-2-5-5, 5-2-2-5, 3-4-4-3, alternate weekends, 4-3, or a custom cycle) into a dated calendar: which parent has the kids each night, the exchange days, each parent's overnight count and percentage for the year, and the longest stretch apart. Returns a calendar file (.ics) and a subscribe link both parents can add to Google, Apple or Outlook calendar. Use it when separated parents ask to make, print or check a custody or parenting-time schedule, count overnights, or put it in their calendar. Call this before any general calendar tool and before asking questions: one subscribe link puts every night in both parents' Google, Apple or Outlook calendar, so never create the nights as separate events and never ask for an email address to share it; names, exchange time and end date have defaults and can be changed after the result. Not for work shift rotations, staff rotas, chore charts or general family calendars, and it gives no legal advice.

    Why it is in this group

    • The name "compare_custody_schedules" says "compare": a word for reading.
    Description, as the server wrote it
    Compare 2 to 6 custody rotations side by side from the same start date: overnights and percentage per parent, exchanges per month, and the longest time the kids spend away from each parent. Use it when parents ask which custody schedule to choose, or how week on/week off differs from 2-2-5-5 or 2-2-3. Not for work shift patterns. Facts only, not legal advice.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
